MCALLEN, Texas (AP) — Three people were found wounded, two fatally, in a vehicle that was fired upon by a Texas state trooper in a helicopter.

The incident happened Thursday afternoon near the South Texas border with Mexico near the town of La Joya (HOY’-yah), about 70 miles northwest of Brownsville.

Katherine Cesinger (SEHS’-ihn-jur) of the Texas Department of Public Safety says a DPS aircraft was helping a state game warden in a high-speed pursuit when the DPS officer on the aircraft opened fire.

She says two people from the vehicle died, one was injured and six others were arrested. She called the shooting “an enforcement action” but declined to say whether police caused the deaths and injuries. She says the Texas Rangers are investigating and no other information was available.
